What is Material Requirements Planning (MRP)?
Material Requirements Planning (MRP) is a system that estimates the requirements for raw materials by combining data from procurement, inventory, and purchase orders with production systems. It aims to ensure availability of the production resources at the right time at the right place to ensure continuity in the production activity, avoid shortages, and improve production efficiency.
ERP software supports Material Requirements Planning by automating demand forecasting, production planning & capacity management, inventory planning, replenishment management, and supplier coordination. By integrating different organisation-wide processes, it builds a structured foundation for a seamless MRP process.

How Material Requirements Planning Works (Step-By-Step Process)
The MRP process consists of four main phases – identifying material requirements, analysing inventory & production resources, production scheduling, and generating plans & reports.
- Identify Material Requirements: First things first, start by identifying the requirements for new materials by analysing your customer orders, demand forecasts, and past sales data.
- Analyse Inventory & Production Resources: Analyse your current inventory levels and production resources. The inventory management software will allocate them appropriately for better efficiency, waste reduction, and lower customer lead times.
- Production Scheduling: Estimate the requirement for labor and production resources. Automate various production-specific processes such as Work Order & Purchase Order generation for better efficiency.
- Generate Exceptional Plans & Reports: Last but not least, your MRP system generates plans for production efficiency and flags potential delays, giving you complete control over the entire process.

How is Material Requirements Planning MRP used in Manufacturing?
MRP in manufacturing environments help decrease inventory through more efficient scheduling, purchase planning, and demand forecasting. MRP will focus on what materials are required to complete manufacturing jobs and when they need to be sourced. This is helpful to minimize stock-outs and reduce excess stock.
One of MRP’s most critical inputs is the bill of materials, or BOM. The BOM is a detailed list of needed raw materials, components, and assemblies in order to manufacture a product. Bill of materials are usually created via order entry systems, reading current inventory levels, and viewing master production schedules.
Bill of materials (BOM) includes hierarchical lists with a top-level representing the finished product and subassemblies below it. BOMs can also have two levels of assembly. One example could be a clock that includes the internal clockwork as well as the outer casing. Usage of MRP in manufacturing, primarily via a clear and understood bill of materials process, will help you complete each manufacturing job while eliminating waste in materials and better coordinating machine usage and labor.
Difference Between MRP and MRP II
Material Requirements Planning (MRP) and Manufacturing Resource Planning (MRP II) are planning approaches that help manufacturers manage production more efficiently. While MRP primarily focuses on calculating material requirements and managing inventory, MRP II takes a broader approach by incorporating additional manufacturing resources, such as labor, machine capacity, production scheduling, and financial planning. Understanding the difference helps businesses choose the right approach for their manufacturing operations.
| Comparison Factor | MRP (Material Requirements Planning) | MRP II (Manufacturing Resource Planning) |
|---|---|---|
| Primary Focus | Material planning and inventory management. | Comprehensive manufacturing resource planning. |
| Main Objective | Ensures materials are available when needed for production. | Coordinates materials, labour, machinery, and other production resources. |
| Key Inputs | Master production schedule, bill of materials (BOM), and inventory records. | MRP inputs, production capacity, labour availability, and additional operational data. |
| Inventory Management | Calculates material quantities and replenishment requirements. | Integrates material planning with broader manufacturing operations. |
| Capacity Planning | Limited capacity planning, often handled separately. | Includes capacity planning for machinery and labour. |
| Production Scheduling | Plans material availability around production schedules. | Supports comprehensive production scheduling and resource coordination. |
| Financial Integration | Limited financial planning capabilities. | Can incorporate manufacturing costs and financial planning. |
| Business Scope | Primarily focuses on material and production requirements. | Covers broader manufacturing planning across operational resources. |
| Best Suited For | Manufacturers focused on material availability and inventory planning. | Manufacturers seeking integrated planning of materials, capacity, and production resources. |
MRP focuses on what materials are needed and when, whereas MRP II expands this approach to consider the broader resources required to manufacture products efficiently. Modern ERP software can extend these capabilities further by connecting manufacturing with procurement, finance, inventory, and other business functions.
